Dear R-users,
We'd like to announce the release of our new package "grouped"
(available from CRAN), for fitting models for grouped or coarse data,
under the Coarsened At Random assumption. This is useful in cases
where the true response variable is known only up to an interval in
which it lies. Features of the package include: power calculations for
two-group comparisons, computation of Bayesian residuals using
Multiple Imputation, capability of fitting models for index-kind data
(e.g., quality of life indexes). Any kind of feedback (questions,
suggestions, bug-reports, etc.) is more than welcome.
Best,
Dimitris Rizopoulos
